Magnetic Door / Window Sensor

Is there a system as sharp and precise as your senses to take care of your home? The Wireless Door and Window Sensor is so intelligent that it sends an alert to your cell phone or email address in the event of a security breach. This sensor creates a magnetic seal between itself and a contact surface. It is placed on the frame of the door or window, while the magnet is placed on the door or window itself. This creates a circuit between the two. If the circuit is broken by opening up the window or door, a signal is sent to the alarm control panel that an entry has been breached, alerting you instantly.
